. MANUFACTURE OF PAPER BOTTLES.

To all whom it may concern Be it known that I, JoHAN GUSTAF V. LANG, a citizen of the United States, and a resident of the borough ofManhattan, city of New York, county and State of New York, have invented certain new and useful Improvements Relating to the Manufacture of Paper Bottles, of which the following is a specification.

per, due to The invention relates to machines for giv-' ing to a tube of paper or similar material the form of a bottle and particularly to the kind of machines by which the surplus pathe gradual transition from the larger diameter of the body to the smaller diameter of the throat and neck, is taken up in laits or folds of one kind or another.

ne object of the present invention is to insure the breaking of the paper in the proper places and thus bring about approximate uniformity of the plaits or folds. It has been found that the action of forcing thepaper down against a form by engaging the tube at equi-distant points around the circumference by loop-forming members suitably spaced to give room for the finished plaits does not in itself bring-about the un1- formity of the plaits or folds. This is due to the fact that the paper which is in the tube varies in structure and strength so that it does not bend and break in the same way in each space between the loop forming members. The loops when formed according to natural tendencies vary considerably in shape and when pressed down the resultingplaits are more -or less distorted and the paper is crumpled up instead of forming a smooth fold. 1

To assist in controlling the forming of the loops there is provided on the face of the loop-forming members thin sheet metal plates which extend into the spaces between said loop-forming members leaving only sufficient room between each of the two adja.

cent thin plates for that part of the paper which connects the loop-portions with therest of the paper that constitutes the throat and neck portion of the bottle. The paper in this loop portion is pressed down over the thin sheet metal plates by means of plaitpressing members and suflicient pressure is Specification of Letters Patent.

with flat springs that constitute yieldable means for engaging the paper in the tube as it is being forced around the neck portion of the mold so as to' form the throat portion of a bottle body.

Anotherfeature of the, inv ntion rela s to the providing of plait-pressing members with yieldable means, preferably in the form of flat springs, so that the loeps will be engaged for substantially their full length by said yieldable members.

As showing a specific embodiment of the invention reference is made to the drawings formin a part of this specification and in which rawings,

The paper tube may be considered to comprise two main members, namely, a bottle body A and a bottom B. This body A is formed by pressing a tube 0 which is preferably a hollow cylinder so that the surplus paper, due to the gradual transition from the larger diameter of the tube to the smaller diameter of the neck or throat, is taken up into .plaits or folds of one'kind or another and as has been previously indicated an object of the present invention is to provide a machine which will do this in a'practical and commercial manner. I

' One form of the machine which will accomplish this is shown in Figs. 4 and 5, while another machine differing somewhat in detail is shown in Figs. 9 and 10. -A machine having a still further difference in its detail of construction is illustrated in- Fig. 11.

- The machine shown in Fig. 4 is partially shown in plan in Fig. 5 and the machine shown in 9 is partially shown in plan in Fig. 10. Each of these machines comprises a frame 1 upon which there is pivotally mounted a series of loop-forming members and a series of plait-pressing members. The loop-forming members of the machine shown in Figsa4 and 5 are designated by the reference character 2 and the plait-press ing members in the same machine are designated by the reference character 3. In the machine shown in Figs. 9 and 10 the loopforming members are designated by 2 and the plait-pre'ssing members by 3, while in the machine shown in Fig. 11 the loop-forming members are designated by the reference character 2 and the plait-pressing members by 3". These loop-forming members and lait-pressing members are pivotally mounted at their lower ends upon the frame so that the upper ends of these members are free to be forced inward toward an inner mold 4. This inner mold 4 is secured to or mounted upon the frame 1, said mold having the shape or configuration of a bottle and arranged with the neck or throat portion of the mold uppermost. This mold may be considered to have a body part a, a throat part b and a neck part c. It will be observed, however, that the throat and neck parts merge into each other and for many purposes the throat may be considered not only to include that portion Which is technically known as the throat but to include also that portion which is'technically known as the neck. It is to be understood,

however, that the word throat is to be given a broad construction as an important feature of the present invention relates to the pressing of a tube in such a manner that the superfluous paper which results from the gradual reduction of diameter is formed into plaits or folds. The plait-pressing and loop-forming members cooperate with this mold 4 and they are operated'so that the loop-forming members are the ones first forced toward the mold and they are followed, so to speak, b the plait-pressing members which lag behind the loop-forming members. These two sets of members constitute what may be referred to as sets of pivoted arms that coiiperate to form in effect a set of duplex members or arms.

Each of the loop-forming members or arms have on their outer sides, to wit, the

sides farthest remote from the' mold 4, surfaces 5 which are shaped so as to provide cam conformations, and the plait-pressing members or arms also 'have on their outer sides, to wit, the sides farthest remote from the mold '4, surfaces 6 which are shaped so as to provide cam conformations. These cam-shaped surfaces 5 and 6 are engaged by rollers 7 that are carried upona ring 8. This ring 8 is operated or forced upwardly through the medium of links 9, arms 10, shaft 11 and handle or arm12. This ring is guided by depending members 13 which slide in screw-members 14. The shaft 11 is carried by bearings 15 and the-construction is such that as thefree end of the arm 12 is forced downwardly by the operator the ring 8 will move upwardly in such a manner that the rollers 7 upon the ring will force the loop-forming-members and the plait-pressing members toward-the mold 4. The cam conformations 5 and 6, however, are constructed so that the plait-pressing members lag behind the loop-forming members. Ah

ejector ring 16 may also be provided at the lower end of the mold 4 and this ejector ring can be moved upwardly through the medium of a link 17 which is connected least has been made of wax paper, and it is therefore advantageous to heat the forming mold to a slight extent. Where this heating is desired burners 19 or any other suitable heating means may be employed. The

mechanism for lifting the ring 8 for ejecting the pressed tube and for heating the mold is shown as being substantially the same in the forms of apparatus shown in Figs. 4 and 9. Each of the loop-forming members of the machine shown in Fig. 4 is provided upon its operating face with a vertically extending spring-member 20 which is secured to the forming-member as by means of a screw 21. Thesespring-members 20 are preferably in the form of'flat springs and about their upper ends there are secured thin curved. plates 22 (see particularly Figs. 5, 6 and 8) which extend laterally relative to the forming members. The ends of these plates 22 extend into the spaces between the loop-forming members 2 but they are constructed of such a length that the adjacent ends 22 22 will leave suflicient space for part of the paper to pass, to wit,

the part designated by the reference charac-,

ter D. The part D is that part of the paper that connects the paper in the loop with the rest of the paper in the throat or neck. The upper and lower ends of each of the spring-members 20 are free to be pressed toward its forming member as the forming. member is forced toward the mold. Each of the plait-pressing members 3' have a flat spring 23 secured to the forming member as by means of a screw 24.. Each of the springs 23 extends substantially vertical and the upper and lower ends thereofare" free so thatthey can be forced toward the plait 5 pressing member 3 as the latter is forced,

toward the mold 1.

It will therefore beobserved that the springs 20 and 23 can adapt themselves to the paper tube C as it is being transformed into' a bottle body and that these springs also can adapt themselves to the bottle body v comprising in combination a mold having the shape or configuration of a bottle,-loop- 1 when it "is in final form.

' In performing the invention the loopforming members are first forced inwardly toward the mold the full distance'andthey are followed in their operation by the plaitpressing members which force' theloops down so as to form plaits or folds which extend over and which engage the ends 22 of the curved plate 22. As the upper end of the spring 20 carries the plate 22 it will 4 be observed that these thin plates 22 can to a lever 18 and it will be manifest that a yield relatively to the forming members as the latter are forced toward the mold.

The machine shown in Figs. 9 and 10 is similar in its -mode of operation to that shown in Fig. 4, but the construction of the parts of the loop-formin members and plait-prmsing members di ers somewhat in detail.

In the machine shown in Fig. 9 there is a depending spring 25 which is suitably secured to the forming-member 2 in a manner so that the lower end of the spring 25 is free to be forced toward the forming member as the latter is forced toward the mold. On the upper end of each of the forming members 2 there is provided a sheet plate means 26, the latter of which comprises hinged wings 27 and 28 the ends 27 and 28 of which are continuously forced toward each other by means of a spring 29. Each to the upper free end of the loop-forming arm 2" and the thin plate 31 may be made of a sprin -steel if desired; its function and mode 0 operation, however, are similar in many respects to thethin plate means 22 described in connection with Fig. 4 and to the thin plate means described in connec-' tion with the form of press shown in Fig. 9..

From what has preceded it will be manifestthat the machines shown inFi'gs. 4, 9

and 11 whiledifi'ering somewhat in detail are similaryin their function and mode of operation. v
